Then, the media playback unit 12 can play back “scent identifying information” that is synchronized with the above-described moving image with sound from the moving image medium with sound 12A.

  In addition, the reproduction system 10 of this embodiment includes a scent information processing unit 13 that generates a control signal for generating a scent based on “scent specifying information”, and a control signal output from the scent information processing unit 13. A scent generating unit 14 that generates a desired scent based on the scent and a cleaning unit 15 that cleans the scent collected from the air are provided.

  The scent information processing unit 13 is provided in the playback device 11 for controlling the scent generation unit 14 and the like based on the “scent identification information” played back by the media playback unit 12. The progress time of the reproduced video and “scent identifying information” are acquired. Based on the acquired “scent specifying information”, the scent information processing unit 13 outputs a control signal calculated so as to provide the viewer with the scent corresponding to the “scent specifying information” at the timing corresponding to the video. 14 for output. That is, the scent information processing unit 13 sends a control signal so that a desired scent defined for the moving image is provided to the viewer through the scent providing device 20 according to the progress defined in accordance with the progress of the moving image with sound. Output.

  In addition, the scent information processing unit 13 calculates a control signal for cleaning the remaining scent remaining in the scent providing device 20 or the like when the provision of the scent to the viewer is terminated in accordance with the moving time of the video. And it outputs to the fragrance generating part 14 or the fragrance providing device 20.

  The timing at which the scent information processing unit 13 cleans the remaining scent is determined by “moving time of moving image” or “time at which scent is not provided” defined from the scent providing time. That is, the cleaning of the remaining scent is performed particularly after providing a kind of scent that tends to leave the remaining scent or when it is desired to avoid turbidity with other scents. Desirably, the time when the scent is not provided is analyzed, and is executed within the time when the scent is not provided. In addition, it is desirable that the washing is performed within 3 seconds, which is a human breathing interval. By implementing it within 3 seconds, the possibility that cleaning can be completed at an optimal time that is not affected by the scent provision schedule increases, so that a plurality of scents can be continuously provided while being changed. Become.

  The scent generating unit 14 is a device that generates a desired scent from a plurality of fragrances, generates a desired scent based on a control signal input from the scent information processing unit 13, and provides the generated scent to the scent Supply to device 20. The fragrance generating unit 14 includes a plurality of fragrance containers C1, C2, and C3 that store liquid fragrances, and flow rate adjusting valves V1, V2, and V3 that adjust the supply amounts of the fragrances from the fragrance containers C1, C2, and C3, respectively.

  Each of the fragrance containers C1, C2, C3 is a cartridge-type container that can be attached to and detached from the fragrance generating unit 14, and in the fragrance containers C1, C2, C3, liquid fragrances that generate different fragrances, that is, types Different fragrances are housed. Since the types of the fragrances in the fragrance containers C1, C2, and C3 are different, a new scent can be generated by mixing the fragrances. Specifically, each flow rate adjustment valve V1, V2, V3 adjusts the opening degree of each valve based on the control signal received from the scent information processing unit 13, and thus the corresponding fragrance containers C1, C2 , A new scent is generated by adjusting the flow rate of the fragrance supplied to the vaporizer 16 from C3.

  The vaporizer 16 is a device that vaporizes the fragrance supplied through the flow rate adjusting valves V1, V2, and V3. The vaporizer 16 mixes the vaporized fragrance and generates a new fragrance. That is, a plurality of fragrances whose amounts are adjusted so that a new fragrance is generated from the fragrances prepared in advance are vaporized and mixed in the vaporizer 16, or mixed and vaporized to produce a new fragrance. Is generated. In addition, although the method using an ultrasonic atomizer is used for the method of vaporizing a fragrance | flavor, the method of heating a fragrance | flavor to vapor | steam, the method of using an ultrasonic atomizer, and a fragrance | flavor as other methods A method of making the particles into fine particles based on the ink jet method and releasing them into the air, a method of taking out the perfume vapor existing on the liquid surface of the perfume, or the like may be used.

  A supply tube T <b> 1 as a first transport pipe for transporting the vaporized and mixed scent to the providing device 20 is extended from the vaporizer 16 to the providing device 20. The supply tube T1 is a resin pipe in which a passage having a diameter of 1 mm to several millimeters capable of transporting the vaporized fragrance is formed. In addition, the supply tube T1 is preferably a so-called Teflon (registered trademark) tube made of, for example, a fluororesin so that the fragrance component does not easily adhere, but various resin tubes can be used.

  That is, the vaporizer 16 dilutes the vaporized fragrance generated based on the control signal from the scent information processing unit 13 with air in accordance with the dilution rate that is also the control signal from the scent information processing unit 13, and also generates the control signal. The scent providing device 20 is supplied at a flow rate determined based on the flow rate. As described above, when the fragrance supplied from the vaporizer 16 reaches the nostril 2 via the fragrance providing device 20, the fragrance is supplied to the fragrance providing device 20 so as to synchronize with the progress of the moving image with sound. That is, the scent information processing unit 13 outputs a control signal to the scent generating unit 14 so that the vaporized fragrance provided to the viewer is synchronized with the progress of the moving image with sound.

  The cleaning unit 15 removes a scent component contained in the air sucked through the providing device 20, and extends to the providing device 20 in order to collect the air through the providing device 20. In addition, a recovery tube T2 as a second transport pipe is connected. The collection tube T2 is a resin pipe in which a passage having a diameter of 1 mm to several millimeters that can transport the collected air is formed. The recovery tube T2 is preferably a so-called Teflon (registered trademark) tube made of, for example, a fluororesin so that the fragrance component is difficult to adhere, but various resin tubes can be used. Thus, by making the number of tubes provided between the regeneration system 10 and the scent providing device 20 two of the supply tube T1 and the recovery tube T2, the flexibility of these tubes is maintained high and the tubes Can suppress the discomfort given to the viewer.

  The cleaning unit 15 is provided with a deodorizer 17 that removes (deodorizes) scent components from the air collected through the connected collection tube T2, and an exhaust pump 18 that supplies negative pressure to the deodorizer 17. ing.

  Thereby, the deodorizer 17 sucks air through the recovery tube T2 by supplying the negative pressure from the exhaust pump 18 to the recovery tube T2, and removes the scent contained in the sucked air from the air. To do. The deodorizer 17 discharges the deodorized air from the exhaust pump 18. By the way, since the fragrance | flavor component contained in a vaporization fragrance | flavor is a volatile component mainly, it is possible to remove the fragrance | flavor component which adhered inside each pipe | tube of the supply tube T1 and the collection | recovery tube T2 by flowing air as a washing | cleaning fluid. It is.

Next, the scent providing apparatus 20 will be described with reference to FIG.
The scent providing device 20 releases the scent supplied from the scent generating unit 14 so as to reach the viewer's nostril 2 and part of the scent released based on the negative pressure supplied from the cleaning unit 15. It is an apparatus for collection, and is attached to glasses 5 as a support. The eyeglasses 5 are supported by the ears of the frames extending rearward on the side of the face, and supported by the nose between the eyes, and are provided with a transmissive lens (or film).

  The scent providing device 20 is held (arranged) on the left side (right side in FIG. 2) of the glasses 5 on the surface side opposite to the face. In the scent providing device 20, a discharge tube 21 that discharges the scent toward the viewer's nostril 2 through the discharge unit 23, and a part of the scent that has not been sucked into the nostril 2 is collected through the suction unit 24. A recovery tube 22 is provided. That is, the spectacles 5 are configured to hold the discharge tube 21, the discharge portion 23, the recovery tube 22, and the suction portion 24 in a predetermined position with respect to the nostril 2. The scent providing device 20 is not particularly limited to the part of the glasses 5 that holds the scent providing apparatus 20 such as the right side or the lower part of the glasses 5.

  The discharge pipe 21 is supplied with a scent generated by the scent generating part 14 through a supply tube T1 connected to the base end thereof, and is supplied through a nozzle-like discharge part 23 provided at the tip thereof. The fragrance gushes toward the nostril 2. The discharge part 23 is for discharging a scent toward the nostril 2 from the vicinity of the left side of the glasses 5 on which it is disposed. That is, although the discharge part 23 is arranged at the lower part of the glasses 5 that is closer to the nose than the eyes and above the nostril 2 (close to the top of the head), the vaporizing fragrance is ejected to the movement path of the vaporized fragrance. A passage 26 through which the vaporized fragrance flows is formed so as to include the nostril 2. In addition, since the rising airflow has arisen in the human body vicinity, the vaporized fragrance | flavor after discharge | release will come to move up according to the rising airflow along a face. For example, the discharge unit 23 can cause the released vaporized fragrance to reach the nostril 2 through a route shown by a route 26A. On the other hand, the vaporized fragrance that has not reached the nostril 2 or has not been inhaled in the routes shown by the routes 26B, 26C, etc., moves upward (in the direction of the eye 3) after passing through the vicinity of the nostril 2. Become. Naturally, the discharge part 23 may be extended and arranged closer to the mouth than the nostril 2. In that case, by releasing the scent toward the nostril 2, the scent can reach the nostril 2 without using the rising airflow due to body temperature.

  The recovery tube 22 has a recovery tube T2 connected to the base end thereof and a tubular suction portion 24 having a number of holes for sucking air at the distal end thereof. That is, the inhalation part 24 collect | recovers fragrance with air, and is arrange | positioned in the lower part of the glasses 5 which are near a nose rather than eyes. Since the inhalation part 24 is disposed along the lower frame of the glasses 5, it is disposed between the nose 1 and the eyes 3 and substantially parallel to both eyes 3. As a result, the recovery pipe 22 can recover the surrounding air from a number of holes for sucking air in the suction portion 24 based on the negative pressure supplied from the recovery tube T2.

  That is, the inhalation unit 24 sucks air above the nostril 2 to inhal a part of the vaporized fragrance that has reached the upper portion of the nostril 2 together with the air before the vaporized fragrance reaches the eyes 3. The inhalation part 24 has a length wider than the lateral width of the nose 1. For example, in the present embodiment, the inhalation part 24 has a length longer than the distance between the eyes 3. As a result, the inhalation part 24 passes through the passage 26 </ b> B that rises after passing the nostril 2 in the lateral direction, and thus passes through the passage 26 </ b> B that is not inhaled into the nostril 2, or the passage 26 </ b> C that rises before reaching the nostril 2. A part of the vaporized fragrance that is not inhaled can be recovered.

  Further, by providing the inhalation part 24 above the nose 1 but at the lower part of the glasses 5 at a position close to the nostril 2, the vaporized fragrance can be collected at a stage where the diffusion into the air is small. The amount of vaporized fragrance that can be recovered increases. Furthermore, since the inhalation part 24 exists in the nostril 2 side rather than both eyes 3, it becomes possible to reduce the quantity of the vaporization fragrance | flavor which raises to the position of eyes 3 or hair and contacts eyes 3 or hair. Thereby, since the vaporized fragrance is discharged and removed at the lower part of the glasses 5 before reaching the eye 3, the risk of the vaporized fragrance acting on the eye 3 is reduced. Furthermore, the possibility that the attachment of the fragrance to the head hair or the remaining of the fragrance in the living space due to the release of the vaporized fragrance for a long time may affect viewing and the like. In this way, the structure in which the vaporizing fragrance discharge tube 21 and the discharge portion 23 and the recovery tube 22 and the suction portion 24 are supported and fixed to the spectacles 5 stabilizes the discharge portion 23 and the suction portion 24 in the nostril 2 of the viewer. It is possible to install the suction part 24 at a position most suitable for removing the vaporized fragrance after being released, and to provide a form that can be easily installed.

  In addition, the scent providing device 20 is provided with a switching device 30 as a switching unit capable of connecting the discharge tube 21 and the recovery tube 22 to the supply tube T1 or the recovery tube T2, respectively.

Therefore, the switching device 30 will be described with reference to FIG.
As shown in FIG. 3A, the switching device 30 is rotatably fitted in a plate-like main body portion 31 having a predetermined thickness and an upper surface circular hole 31 </ b> A formed in the main body portion 31. A disc-shaped movable portion 33 is provided. The hole 31A of the main body 31 is recessed in the thickness direction of the main body 31, and the movable portion 33 is configured such that the disk rotates around the circle center of the hole 31A in the inserted hole 31A. ing. The main body 31 is provided with a small motor that rotates the movable portion 33, and the rotation angle of the movable portion 33 is adjusted by controlling the rotation angle of the small motor. The small motor is electrically connected to the scent information processing unit 13 through a wiring (not shown), and the movable unit 33 is set to a predetermined angle by drive control by the scent information processing unit 13.

  The main body part 31 is provided with four connection parts 32a to 32d. The connection part 32a has an end part of the supply tube T1, and the connection part 32b has an end part (base end) of the scent discharge pipe 21. The end portion (base end) of the recovery tube 22 is connected to the connection portion 32c, and the end portion of the recovery tube T2 is connected to the connection portion 32d. Each of the connection portions 32a to 32d has a passage formed in the thickness of the main body 31, and each of the formed passages opens an outer opening at an end of each connection portion 32a to 32d, The opening is opened on the side surface of the hole 31 </ b> A of the main body 31. That is, each passage communicates the end portions of the corresponding connection portions 32 a to 32 d with the side surface of the hole 31 </ b> A of the main body portion 31. Note that the outlets of the passages opened in the hole 31A of the main body 31 are arranged at substantially equal angular intervals with respect to the circular shape in the hole 31A of the main body 31, that is, at approximately 90 ° intervals.

  The movable portion 33 is provided with a first communication passage P1 and a second communication passage P2. Since the first and second communication passages P1 and P2 have openings at both ends of the passages formed on the side surfaces of the movable portion 33, that is, within the thickness of the disk, the movable portion 33 is formed in the hole 31A of the main body portion 31. When fitted, it can be opposed to the openings inside the connecting portions 32a to 32d formed on the side surface of the hole 31A. Further, the first communication passage P1 is provided so that the openings at both ends thereof are spaced approximately 90 ° from the center of the circle of the movable portion 33, and the second communication passage P2 is provided at both ends thereof. Are provided at positions that are substantially 90 ° apart from each other and that are also substantially 90 ° apart from the opening of the adjacent first communication passage P1. In other words, the movable portion 33 has one opening of the first communication passage P1, the other opening of the first communication passage P1, one opening of the second communication passage P2, and the second communication every 90 °. The other opening of the passage P2 is disposed.

  Therefore, as shown in FIG. 3A, when the switching device 30 is arranged at a predetermined angle with respect to the main body portion 31, the switching device 30 is placed in the opening on the side surface of the hole 31 </ b> A of the passage of the connection portion 32 a. One opening of the one communication passage P1 is opposed to communicate the passage of the connecting portion 32a with the first communication passage P1. At this time, the other opening of the first communication passage P1 that is shifted by 90 ° faces the opening on the side surface of the hole 31A of the passage of the connection portion 32b, and the passage of the connection portion 32b and the first communication passage P1. Communicate. Similarly, one opening of the second communication passage P2 that is further shifted by 90 ° is opposed to the opening on the side surface of the hole 31A of the passage of the connection portion 32c, and the passage of the connection portion 32c and the second communication passage. P2 communicates. Similarly, the other opening of the second communication passage P2 that is further shifted by 90 ° is opposed to the opening on the side surface of the hole 31A of the passage of the connection portion 32d, so that the second communication with the passage of the connection portion 32d is performed. The passage P2 communicates with the passage P2.

  That is, the supply tube T1 communicates with the discharge pipe 21 via the first communication passage P1 of the movable portion 33, and the recovery tube T2 passes through the second communication passage P2 of the movable portion 33. It will be communicated to. Thereby, the switching device 30 implements a so-called first connection mode in which the supply tube T1 is connected to the discharge tube 21 and the recovery tube T2 is connected to the recovery tube 22.

  In addition, the movable part 33 can rotate 90 ° with respect to the main body part 31. For example, when the movable portion 33 is rotated 90 ° clockwise from the state shown in FIG. 3A, the state becomes as shown in FIG. In other words, the movable portion 33 rotated by 90 ° has one opening of the first communication passage P1 opposed to the opening on the side surface of the hole 31A of the passage of the connection portion 32d, whereby the passage of the connection portion 32d is connected to the first communication passage. Communicate with the passage P1. Further, the other opening of the first communication passage P1 that is disposed 90 degrees away from the opening on the side surface of the hole 31A of the passage of the connection portion 32a is opposed to the passage of the connection portion 32a and the first communication passage P1. To communicate. Similarly, by making one opening of the second communication passage P2 further displaced by 90 ° opposite to the opening on the side surface of the hole 31A of the passage of the connection portion 32b, the second communication passage P2 is connected to the passage of the connection portion 32b. The passage P2 is connected. Further, the other communication passage P2 disposed at a 90 ° angle is opposed to the opening on the side surface of the hole 31A of the connection portion 32c so that the second communication passage is connected to the connection portion 32c. Communicate P2.

  That is, the supply tube T1 is connected to, that is, communicated with, the recovery tube T2 via the first communication passage P1 in the movable portion 33, and the discharge pipe 21 is routed through the second communication passage P2 in the movable portion 33. As a result, the recovery pipe 22 is connected, that is, communicated. Thereby, the switching apparatus 30 implements the 2nd connection aspect which connects supply tube T1 to collection | recovery tube T2.

  In the present embodiment, the scent information processing unit 13 drives and controls the small motor so that the switching device 30 is in the first connection mode when supplying the vaporized fragrance, and when the scent is washed, the switching device 30 is used. The small motor is driven and controlled so as to be in the second connection mode. That is, when cleaning the scent, the scent of the cleaning fluid flowing through the supply tube T1 is released through the discharge tube 21 in order to achieve the second connection mode in which the connection between the discharge tube 21 and the supply tube T1 is broken. Nothing is supplied from the unit 23 to the viewer. In other words, the channel is cleaned with the switching device 30 in the second connection mode, so that the possibility of the viewer touching the cleaning air or the fragrance vaporized by the cleaning is reduced, and the smell generated by the cleaning is reduced. The viewer is prevented from feeling.

(Function)
In this scent supply system, by setting the switching device 30 to the first connection mode, the vaporized fragrance generated by the scent generating unit 14 is supplied to the discharge pipe 21 and ejected from the discharge unit 23 toward the nostril 2. . In addition, by operating the exhaust pump 18, the recovery pipe 22 supplied with negative pressure recovers air containing vaporized fragrance from the suction portion 24. Thereby, the remaining incense which consists of the vaporization fragrance | flavor etc. of the nostril 2 vicinity can be reduced.

  On the other hand, the scent supply system stops the generation of the vaporized fragrance by the scent generation unit 14 and sets the switching device 30 to the second connection mode, thereby changing the recovery tube T2 supplied with negative pressure to the supply tube T1. Direct connection is made to collect the vaporized fragrance retained in the supply tube T1 and the remaining fragrance attached. Thereby, supply tube T1 is wash | cleaned and the remaining incense remaining in supply tube T1 etc. reduces.

  In other words, the vaporized fragrance containing the volatile component is changed in the fragrance information processing unit 13 by switching the connection mode of the switching device 30 to the second connection mode during the time period when the fragrance is not provided in accordance with the progress of the moving image. It is possible to remove perfume components adhering to the inside of each of the supply tube T1 and the recovery tube T2 by flowing air as a cleaning fluid. In addition, since the cleaning fluid (air) is only flown in one direction of the supply tube T1, for example, cleaning can be performed in a shorter time than when the cleaning fluid is reciprocated. The configuration on the scent generating unit 14 side that does not have a configuration for collecting the cleaning fluid can be simplified.

As described above, according to the scent supply device of the present embodiment, the effects listed below can be obtained.
(1) Since a part of the scent discharged from the discharge part 23 is collected by the suction part 24, the remaining scent in the air around the nostril 2 can be reduced. Normally, a rising airflow is generated on the side of the human body due to body heat. Therefore, for example, by allowing the scent to reach the nostril 2 from the mouth side and providing the inhalation part 24 closer to the eyes 3 than the nostril 2, the scent of the released scent by the ascending air current is moved ahead of the movement path 26. The inhalation part 24 is arranged, and the scent can be easily collected in the inhalation part 24.

  In addition, since the remaining scent in the air is reduced by the collection, even if the scent is switched according to the timing such as a change that occurs in the visual and auditory senses due to the moving image, the possibility that the scent before and after the switching is mixed is reduced. Thereby, the scent providing device can prevent the plurality of scents provided by switching from being mixed before and after switching.

Furthermore, since the inhalation part 24 can be arrange | positioned so that the movement of the fragrance from the discharge | release part 23 to the nostril 2 may not be obstructed, the nasal passage reachability of the fragrance can be maintained high.
(2) Since the possibility that the released scent can be recovered increases because the width of the suction portion 24 is wide, it is expected to reduce the remaining scent.

  In addition, by disposing the suction part 24 between the nostril 2 and the eyes 3, the amount of scent reaching the eyes 3 and the hair can be reduced. As a result, it is possible to prevent the possibility that the scent component reaching the eye 3 adheres to the eye 3 or the scent component reaching the head adheres to the hair.

  (3) Since the discharge unit 23 and the suction unit 24 are held by the glasses 5 attached to the head, it is possible to release the scent and collect the scent in the vicinity of the nose 1. Thereby, the scent providing device can collect more scent that has been released but not absorbed by the nostril from the air.

  Moreover, since the discharge | release part 23 can be arrange | positioned in the vicinity of the nose 1, the nasal passage reach | ability of a fragrance is maintained highly, and the quantity of the fragrance to discharge | release can be decreased. This also reduces the possibility of mixing the scent with less remaining scent.

  (4) Since the glasses 5 are supported by the ear and the nose 1, the discharge part 23 and the inhalation part 24 can be arranged at a position close to the nostril 2. Thereby, it becomes possible to further increase the ratio of the recovered scent or reduce the amount of the scent to be released.

  (5) The suction part 24 can be disposed on the glasses 5. Usually, since the frame of the glasses 5 is disposed above the nose 1, it is easy to dispose the suction part 24 at an appropriate position.

  (6) The switching device 30 switches the connection destination of the supply tube T1 to the discharge portion 23 or the recovery tube T2 via the discharge tube 21 and the connection destination of the recovery tube T2 to the suction portion 24 or the supply via the recovery tube 22 Switch to tube T1. Thereby, according to the 1st connection mode, fragrance providing apparatus 20 can collect fragrance from discharge part 23 while releasing fragrance from discharge part 23. On the other hand, in the scent providing device 20, according to the second connection mode, since the supply tube T1 and the recovery tube T2 are connected, the cleaning air flows between the supply tube T1 and the recovery tube T2. Thus, the remaining scent of the supply tube T1 can be cleaned without discharging the cleaning air from the discharge portion 23. Thereby, the scent providing device can more suitably prevent the plurality of scents provided by switching from being mixed before and after switching.

  Moreover, since the movable part 33 driven by a small motor can shorten the switching time by the switching device 30, the supply tube T1 can be cleaned in a short time. As described above, if the remaining scent can be washed in a short time, the number of supply tubes T1 used for transporting the scent to be released can be maintained at one even if the plurality of scents are switched. Also become. Furthermore, since the number of tubes is set to the minimum two, the flexibility of the tubes is maintained, so that it is possible to suppress the uncomfortable feeling that the viewer feels in the supply tube T1 and the collection tube T2.

  (7) The switching device 30 changes the direction of the first communication path P1 and the second communication path P2 by changing the direction by rotation, and switches between the first connection mode and the second connection mode. As described above, since the first connection mode and the second connection mode can be performed by changing the directions of the first communication path P1 and the second communication path P2 by the switching device 30, the connection mode can be easily changed.

  (8) A scent corresponding to an image or video (environment light) transmitted through the glasses 5 can be provided. In this way, a strong impression can be given to the user by adding a scent to the image or video transmitted through the glasses 5. This is the same even if the ambient light transmitted through the glasses 5 is a landscape or the like.

  The head-mounted display 6 as a support has a large eyeglass shape, is a display that is used by being fixed to a viewer's head with a belt, and is a small display that displays an image at a close distance of the human eye. A display is provided for each of the left and right eyes. Accordingly, the head mounted display 6 is a display that can make the viewer feel as if they are in a virtual reality space in a usage state that does not interfere with human movement. Moreover, the head mounted display 6 can also display a different image on each of the left and right small displays for stereoscopic viewing.

  Because of this structure, the viewer cannot see through the tip of the head mounted display 6. However, in this embodiment, the head-mounted display is also defined as glasses because it provides an image to both eyes of the human body, and an optical system that covers both eyes of the human body for the purpose of providing different images to both eyes. In the case of a system, it is also defined as stereoscopic glasses.

  The head mounted display 6 is connected to the playback device 11 of the playback system 10 so as to be able to acquire image information, and provides a video reproduced by the playback device 11 to the viewer's eyes. That is, the head mounted display 6 is connected to the playback apparatus 11 by wiring, but may be wireless connection as well as wired connection as long as image information can be acquired.

  The head mounted display 6 is equipped with a sensor such as a gyro, and is provided to both eyes of the viewer who is wearing it according to a sensor signal output from the gyro or the like that has detected an operation including the orientation of the viewer. It may have a function of changing In other words, for example, the head mounted display 6 may display an image in a facing direction.

  A suction portion 25 is provided on the outer surface 6A on the surface of the head mounted display 6 that does not face the face (eyes), along the circumferential shape of the outer surface 6A. The suction part 25 has the same structure as the suction part 24 of the first embodiment, and sucks air in the vicinity of the suction part 25 based on the negative pressure applied from the recovery tube T2 via the recovery pipe 22. .

(Function)
When the vaporized fragrance is ejected from the discharge portion 23 toward the nostril 2, the vaporized fragrance reaches the lower portion of the nostril 2 through a route such as the route 26, and is sucked into the nostril 2 through a route such as a route 26A along the rising airflow. Is done. On the other hand, as shown in the route 26C, the vaporized fragrance that does not reach the lower side of the nostril 2 or has passed the lower side of the nostril 2 as shown in the route 26B is then moved upward (in the direction of the eye 3). ) A part of the vaporized fragrance is absorbed by the suction part 25 arranged at the lower part of the head mounted display 6. However, the vaporized fragrance that has not been absorbed by the lower suction part 25 moves toward the upper part of the head mounted display 6 as shown by the path 26D and the path 26E. In this case, since the suction part 25 is also arranged on the upper part of the head mounted display 6, a part of the vaporized fragrance that has moved by the suction part 25 on the upper part as shown in the paths 26D and 26E is collected. be able to.

As described above, according to the scent supply device of the present embodiment, in addition to the effects (1) to (8) described in the first embodiment, the effects listed below can be obtained. Become.
(9) Since the scent providing device 20 can be provided in the head mounted display 6, the scent corresponding to an image or a moving image can be switched and provided in a short time. In this way, by adding a scent synchronized with an image or video, it is possible to strongly give the viewer a sense of realism.

  (10) In particular, the so-called head mounted display 6 provided with a small display corresponding to each of the eyes allows the viewer to preferably experience virtual reality. By providing the scent providing device 20 capable of switching the scent in accordance with an image or a moving image on the head mounted display 6 as described above, it is possible to strongly give the viewer a sense of virtual reality.

(Third embodiment)
Hereinafter, a third embodiment of the scent supply apparatus according to the present invention will be described with reference to FIG.
Although this embodiment is different from the first embodiment in that the cleaning liquid is used for cleaning the supply tube T1, the other configurations are the same. For the convenience of explanation and explanation, the same numbers are assigned to the same components, and explanations thereof are omitted.

  The regeneration system 10 is provided with a cleaning liquid supply unit 38 that allows the cleaning liquid to flow into the supply tube T1, and a cleaning liquid recovery unit 39 that recovers the cleaning liquid from the recovery tube T2. In the cleaning, the switching device 30 is switched to the second connection mode.

  The cleaning liquid supply unit 38 is connected to a supply tube T <b> 1 extending from the vaporizer 16 to the switching device 30 via a merging unit. The cleaning liquid supply unit 38 can receive a signal from the scent information processing unit 13, receives the cleaning start signal output from the scent information processing unit 13, and discharges the cleaning liquid to flow into the supply tube T1. . The cleaning liquid includes, for example, water, ozone water, alcohol, or the like, and can dissolve and remove the fragrance component adhering to the piping such as a tube in the path through which the cleaning liquid flows.

  The cleaning liquid recovery unit 39 is a so-called gas-liquid separator, and flows from the supply tube T1 through the switching device 30 through the recovery tube T2 to temporarily suck the cleaning liquid, where the liquid is separated and only the gas is cleaned. Is output. That is, the cleaning liquid recovery unit 39 causes the cleaning liquid recovered from the upper inlet to stay in the lower part, while allowing the cleaning unit 15 to discharge the gas contained in the cleaning liquid and the air recovered when supplying the fragrance from the upper outlet.

  Also in the present embodiment, since the discharge pipe 21 is disconnected from the supply tube T1 by performing the flow path cleaning after the switching device 30 is set to the second connection mode, it is possible to view the fragrance or the cleaning liquid vapor generated by the cleaning. The possibility of touching the viewer is reduced, and the viewer is prevented from feeling the smell generated by the cleaning.

(Function)
By switching the connection mode of the switching device 30 to the second connection mode by the scent information processing unit 13 and flowing the cleaning liquid from the cleaning liquid supply unit 38 during the time period when the fragrance is not provided in accordance with the progress of the moving image, the supply tube T1 and It is possible to remove the fragrance component adhering in each tube of the collection tube T2. In addition, since the cleaning liquid is allowed to flow only in one direction of the supply tube T1, for example, compared with a case where the cleaning liquid is reciprocated, the time required for cleaning can be shortened, and a fragrance that does not collect the cleaning liquid is generated. The configuration on the part 14 side can be simplified.

As described above, according to the scent supply device of the present embodiment, in addition to the effects (1) to (8) described in the first embodiment, the effects listed below can be obtained. Become.
(11) By using the cleaning liquid for cleaning the supply tube T1, the fragrance component adhering in the supply tube T1 can be more reliably cleaned. Thereby, a residual fragrance is removed suitably and fear that a fragrance will mix is prevented.

  (12) Since the cleaning liquid is allowed to flow in one direction of the supply tube T1, the time during which the cleaning liquid is supplied to the supply tube T1 can be shortened, that is, no time is required for recovery. Can be shortened. As a result, the scent can be switched in a shorter time.

(Fourth embodiment)
Hereinafter, 4th Embodiment of the fragrance supply apparatus which concerns on this invention is described according to FIG.
The present embodiment is different from the first embodiment in that the switching device 40 is different from the switching device 30 in the first embodiment, but the other configurations are the same. Differences will be mainly described, and for convenience of description, the same numbers are assigned to the same components, and descriptions thereof are omitted. In this embodiment, the cleaning liquid supply unit 38 connected to the supply tube T1 in the third embodiment is connected to the recovery tube T2. In the third embodiment, the cleaning liquid supply unit 38 is connected to the recovery tube T2. It is assumed that the cleaning liquid recovery unit 39 that has been connected is connected to the supply tube T1. As in the third embodiment, the cleaning liquid supply unit 38 receives the cleaning start signal output from the scent information processing unit 13 and discharges the cleaning liquid.

  As shown in FIG. 6A, the switching device 40 is provided with a plate-like main body 41 having a predetermined thickness. The main body portion 41 is provided with four connection portions 42a to 42d, the end portion of the supply tube T1 is connected to the connection portion 42a, and the end portion (base end) of the discharge tube 21 is connected to the connection portion 42b. The end portion (base end) of the recovery tube 22 is connected to the portion 42c, and the end portion of the recovery tube T2 is connected to the connection portion 42d. The switching device 40 has a communication passage P11 for supply as a first communication passage that allows the connection portion 42a and the connection portion 42b to communicate with each other, and a second communication passage that allows the connection portion 42c and the connection portion 42d to communicate with each other. A collection passage P12 for recovery is provided. In addition, the gas is allowed to pass through the connection portion 42b side of the supply communication passage P11 and the connection portion 42c side of the recovery communication passage P12, respectively, while the liquid can be prevented from passing therethrough. A gas-liquid separation film 43 as a gas-liquid separation unit 2 is installed in such an arrangement as to block the passage.

  The gas-liquid separation membrane 43 is a thin film having a water repellency of, for example, porous PTFE (polytetrafluoroethylene) having a thickness of 80 μm to 200 μm, and a large number of pores having a pore diameter of 0.1 to 0.2 μm are formed in the membrane. Has been. That is, since the gas-liquid separation membrane 43 is configured to allow gas to pass therethrough, it can transmit the vaporized fragrance supplied from the supply tube T1, and from the recovery pipe 22 (suction part 24). The recovered air can be permeated. Thereby, the vaporized fragrance | flavor supplied from supply tube T1 is supplied to the discharge tube 21, and the air collect | recovered from the collection tube 22 is collect | recovered by the collection tube T2.

  A communication hole 44 is formed between the supply communication path P11 and the recovery communication path P12 and closer to the connection part 42a and the connection part 42d than the gas-liquid separation film 43. A valve body 45 that switches between communication / non-communication of the communication hole 44 is provided on the supply communication path P11 side of 44 with the connection portion 42b side as a fixed point. The valve body 45 is a valve made of a resin material or a rubber material, and is elastically deformed with a fixed point as a fulcrum when pressed, but is sized to cover the opening of the communication hole 44. Therefore, it is not elastically deformed by the pressure received from the supply communication passage P11 side. That is, the discontinuity between the supply communication path P11 and the recovery communication path P12 is maintained. On the other hand, when the valve body 45 is pressed from the recovery communication passage P12 side, the valve body 45 moves into a space constituting the supply communication passage P11 with the fixed point as a fulcrum, so that the recovery communication passage P12 is connected to the supply. Communicate with the passage P11.

  For this reason, when the cleaning liquid is supplied from the recovery tube T2, the permeation of the cleaning liquid is blocked by the gas-liquid separation membrane 43, the pressure in the recovery communication passage P12 increases, the valve body 45 is pressed and released, and the communication hole 44 forms a short-circuit passage P13 communicating with the supply communication passage P11. Then, the cleaning liquid flows through the short-circuit passage P13 from the recovery communication passage P12 toward the supply communication passage P11. At this time, if the supply tube T1 is set to a negative pressure, the cleaning liquid can be easily moved from the recovery communication passage P12 to the supply communication passage P11. Since the cleaning liquid does not move from the gas-liquid separation membrane 43 to the recovery pipe 22 or the discharge pipe 21, the cleaning liquid is discharged from the discharge section 23 via the suction pipe 24 or the discharge pipe 21 via the recovery pipe 22 to the viewer. There is nothing that makes you feel uncomfortable.

  That is, the switching device 40 is communicated with the communication hole 44 by the valve body 45 being passively operated according to the pressure in the recovery communication passage P12 and the supply communication passage P11. Then, the cleaning liquid supplied from the recovery communication passage P12 and flowing into the supply communication passage P11 flows through the supply tube T1 connected to the supply communication passage P11 to clean the remaining incense in the supply tube T1. It is like that.

  In the present embodiment, by supplying the vaporized fragrance from the supply tube T1, the switching device 40 connects the supply tube T1 to the discharge tube 21 and connects the recovery tube T2 to the recovery tube 22 so-called first connection. Aspect will be implemented. On the other hand, by supplying the cleaning liquid to the recovery tube T2, the switching device 40 comes to implement the second connection mode in which the supply tube T1 is connected to the recovery tube T2.

As described above, according to the scent supply device of the present embodiment, in addition to the effects (1) to (8) described in the first embodiment, the effects listed below can be obtained. Become.
(13) The switching device 40 has a communication passage P11 for supplying the fragrance (vaporized fragrance) supplied from the supply tube T1 and the gas-liquid separation membrane 43 as a first connection mode by closing the communication hole 44 by the valve body 45. The gas recovered from the recovery pipe 22 is transported to the recovery tube T2 via the gas-liquid separation membrane 43 and the recovery communication path P12. On the other hand, the switching device 40, as a second connection mode by opening the communication hole 44 by the valve body 45, is configured to connect the communication passage P12 for recovery by the cleaning liquid (liquid) that cannot pass through the gas-liquid separation membrane 43 supplied to the recovery tube T2. The valve body 45 is opened by the increase in internal pressure, and the cleaning liquid is caused to flow from the recovery communication passage P12 to the supply communication passage P11. That is, the change of the first and second connection modes by the switching device 40 is performed by switching between supplying the vaporized fragrance (gas) to the supply tube T1 or supplying the cleaning liquid (liquid) to the recovery tube T2. Thereby, it becomes possible to easily switch between supply and collection of fragrance and cleaning of the tube.

  (14) A cleaning liquid is flowed from the recovery tube T2 toward the supply tube T1, and the recovery tube T2 and the supply tube T1 are cleaned. Thereby, by using this switching device 40, the recovery tube T2 and the supply tube T1 can be more easily cleaned.

(Other embodiments)
In addition, each said embodiment can also be implemented in the following aspects, for example.
In the first embodiment, the spectacles 5 are the transmissive type, and in the second embodiment, the spectacles are the head mounted display 6. However, the present invention is not limited to this, and the glasses may have a polarization function and a shutter function. For example, as shown in FIG. 7, the right and left lenses (films) are attached to the left and right lenses (films) by separately providing glasses 7 as a support with lenses 7A and 7B (or films) on the right eye side and left eye side, respectively. It can be configured by a transmission type polarizing plate having polarization planes orthogonal to each other, or can be provided with a shutter function configured by liquid crystal or the like on each of the right eye side and the left eye side.

  For example, when the left and right lenses (or films) are composed of polarizing plates, different images can be transmitted to the right eye and the left eye. That is, an image display device that displays images displays images to be presented to both the left and right eyes using mutually orthogonal polarized light, so that the viewing angle can be mutually viewed in combination with the above glasses. Different images can be displayed to provide stereoscopic (3D) images.

  In addition, the shutter function provided separately for the right eye side and the left eye side can provide different images for the left and right eyes by switching between opening and closing so that only one of the shutters can be opened according to the timing of the television. Therefore, a stereoscopic image can be provided. In this case, the glasses 7 may be connected so that the reproduction system 10 can perform shutter control.

  These light transmissive glasses for stereoscopic viewing using the polarization function and the shutter function can be particularly defined as stereoscopic glasses for the purpose of providing different images to both eyes. That is, by applying the scent providing device to the stereoscopic glasses, it is possible to give the viewer a sense of realism with respect to the scent.

  Further, as the spectacles, an image may be superimposed on the transmitted light such as a lens via a half mirror. In other words, the scent may be provided to spectacles that provide an image superimposed on a surrounding environment such as a landscape, or transmitted ambient light such as an image or video. In this way, a strong impression can be given to the user by adding a scent to the surrounding environment such as landscape, images, and video.

  In the third embodiment, the case where the cleaning liquid supply unit 38 and the cleaning liquid recovery unit 39 are independent is illustrated. However, the cleaning liquid supply unit is not limited to this, and the used cleaning liquid recovered by the cleaning liquid recovery unit is used. May be returned to the cleaning liquid supply section and used repeatedly. Since the fragrance component taken into the cleaning liquid by the cleaning is extremely small, even if the same cleaning liquid is used a plurality of times, the cleaning performance of the cleaning liquid is not greatly reduced.
